Autosize all columns function crashes when there is rowspan configuration set for columns.

[vasyl-hordynskyy]

• what edition are you using - enterprise
• version for @inovua/reactdatagrid-enterprise - 5.9.4

Relevant code or config
Rowspan is enabled for cels.

What you did:
I used the default example for cell rowspan and colspan from the documentation (https://reactdatagrid.io/docs/cell-rowspan-and-colspan). In this example, when I open the column menu for a specific column and select the 'Autosize all columns' option, the column widths do not change, and an error is logged in the console.
What happened:
Error in console cannot read properties of undefined on Autosize all columns menu click.
